D-500L Firmware V-5.8
K35D03-EN - 53 -
The unit features waveform display together with a precision harmonic analyzer for both mains and
genset voltages and currents. Both phase to neutral and phase to phase voltages are available for
analysis, thus 18 channels in total are possible.
Available channels are:
Mains volts: V1, V2, V3, U12, U23, U31
Mains currents: I1, I2, I3
Genset volts: V1, V2, V3, U12, U23, U31
Genset currents: I1, I2, I3
Scopemeter Display
The waveform display memory is of 100 samples length and 13 bit resolution, with a sampling rate of
4096 s/s. Thus one cycle of a a 50Hz signal is represented with 82 points. The vertical scale is
automatically adjusted in order to avoid clipping of the signal.
The waveform is displayed on the device screen, and with more resolution on PC screen through the
RainbowPlus program.
The display memory is also available in the Modbus register area for third party applications. For more
details please check chapter “MODBUS Communications”.
The waveform display is updated twice a second. All channels may be scrolled using buttons.
In order to enable display and analysis of mains currents, current
transformers must be placed at load side.
